San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Why Glue Traps Are An Inhumane Option For Rats
Glue Traps Won't Kill An Animal:
A glue trap will not humanely kill an animal; the glue is not toxic in any way. A glue trap merely traps the animal in one place and ensures that over the course of several days the animals will die of dehydration, starvation, or eventually suffocation. Many animals end up removing their own skin and fur to get away. Some rats will even take off some of their limbs trying to get free and can be successful in doing so with glue traps.
They Can Be Harmful To Your Pets:
Getting a pet stuck in a glue trap can be just as damaging. If your pet happens to stumble across one of these traps they could end up with it stuck to their fur and the need for shaving or immediate medical care.
They Lead To Harmful Smells In Your Home:
Because the animal will likely die of suffocation this can often lead to the glue trap starting to smell depending on the area of your home that it is in. Rather than having harmful odors throughout your home, it would be wise for you to consider a different option that is much faster for killing a rat.
They Don't Remove The Problem:
Glue traps don't target nests and they don't take away the chance that rats could continue to breed and increase their numbers. Choosing a different type of trap could be a better option for targeting parents that can breed in the area.
They Don't Seal Up Other Areas Where Rats Could Get In:
A glue trap is a temporary solution and it will only work on the rats that you have inside your home. If rats find a different area to get into or they are able to burrow deeper, the glue trap will not stop them.
Rats Are Quite Intelligent:
If you have a glue trap that's in a regular spot, rats may soon start to avoid it over time. No matter how tempting the glue bait may seem, a rat may actively avoid a trap after it's been in an area for some time.
